Bromoform is a naturally-occurring halogenated compound found at elevated levels in certain red seaweeds - most notably species of Asparagopsis. In ruminant nutrition research, bromoform has become a focal point because it inhibits the final step of methanogenesis in the rumen (the methyl-coenzyme M reductase pathway).

 

When present at appropriate levels, seaweeds rich in bromoform can markedly reduce enteric methane emissions—an opportunity with implications for climate targets and for low-carbon animal production systems.

 

Bromoform concentrations vary widely by species, season, growing location, and post-harvest handling, so a nominal inclusion rate or a species name alone is not a reliable guide to potency. Over- or under-dosing can either blunt the methane-reduction effect or raise avoidable safety concerns. Robust quantification allows formulators to standardise blends, nutritionists to set evidence-based inclusion rates, and producers to demonstrate due diligence to customers and regulators.

 

Accurate determination is technically demanding. Bromoform is volatile and susceptible to loss during drying, milling, and extraction; it can also partition into headspace during storage. Sampling protocols, tight containers, cold/rapid shipment, and controlled pre-analysis handling are therefore critical to prevent artefacts.

 

At Celignis we have developed an optimised analytical method for bromoform content, suitable for seaweed samples and seaweed-derived materials (e.g. extracts, residues etc.). 

Constituents Determined

For every constituent determined via wet-chemical analysis each sample is analysed in duplicate and we provide the compositional data for each replicate along with the average value and the standard deviation between the duplicates. Our analytical protocols typically provide results with a high level of precision, as detailed here.

Sample Weight Requirements

Under nornal conditions there is a minimum requirement of 5g of sample for this analysis package with a recommended weight of 20+g of sample.

However, it may be possible for us to undertake the anaysis with lower quantities than the minimum specified above. Please email us at info@celignis.com to find out.
